Improvement in portable buildings



UNITED STATES FRANCIS M. BAIN, OF DELAWARE, OHIO.

Y IMPROVEMENT IN PORTABLE BUILDINGS.

Specication forming part of Letters Patent No. 117,721, dated August 8, 1871.

To all whom it may concern.-

Be it known that I, FRANCIS M. BAIN, of the town of Delaware, in the county of Delaware and State of Ohio, have made certain Improvements in Portable Buildings, of which the following is a specification:

My invention relates to the construction of portable buildings of boards or plank in side and roof-sections, of any desired number to suit the size ofthe building required. These sections are joined together to form the proper angles, and fastened in such manner as to obviate the necessity of frame-work or corner-posts. The fastenings used are the same in a building of greater or lesser dimensions, and allow the angles formed by the joined sections to be increased or decreased so that a section of the side and a corresponding roof-section may be added to or taken from the building without impairing its efiiciency or affecting the strength of the fastenings. A part oil my invention consists in the application, to the outer portion ofthe angles, of a curved weather-strip, its shape permitting its adjustment to the angle in altering the size oi' the building, While it completely excludes the wind and rain from the joint, and also operates, in connectionwith the peculiar-shaped bolts which fasten it to the building, as a binder to strengthen and support thesame.

The roof-sections may be carried to a point, or a cone oi' sheetmetal may be iitted at the sunt mit, as shown. This cone may be used as a ventilator or flue, and should be made with a circular shaft in order to more readily iit the roof-section to it, their points being rounded out for the purpose.

stringer to which the siding may be nailed at the bottom or bolted atY that part; also enlarge ment of building by moving side section A on the left to A. Fig. 4 is an enlarged plan view of angle of side section, showing the hook-bolt as attaching the side sections with its washer and nut clamping the weather-strip on the outside. Fig. 5 is a view of one of' the washers. Fig. G'is a view of a sub-section of roof, showing the lug-bolt and its fastenings, which Fig. 3 is a plan view of side sec- Y tion shown in Fig. 1, showing also a'sill or pierces the holes in top of siding inside, its object being to prevent the roof from being raised up off the siding by wind.

A is the side section of the building; B, roofsection of same; C, the cone.' Both roof and sides are made of boards or plank oi' any thickness required, with battens nailed across to keep them together. On the inside of the plank of each section which forms the angle are holes e, or a groove, e', Fig. 2, near its edge, into which the ends of the hooks of bolt h pass, it being thrust through the angle (holes being made for the purpose) from the inside, and secured by the curved washer o and nut a on the outside. The wash er is diamond-shaped, and curved to iit the rounded form of the strip YV, which latter is hollowed on the inside to accommodate it to any required angle, and is made thick in the middle to give it strength, and thinned down at the edges to make a tight joint. hooks on bolt h have sufficient play (when the bolts are slightly loosened by unscrewing the nut n) to allow them to operate in the manner of a hinge to some extent, as seen in the dotted lines ot' e, Fig. 4, showing the holes larger than the ends ofthe hooks. The lower battens of the roof-sections B prevent their slipping outward. They are further secured to the side sections by the lug-bolts Z, which pierce the top ends of the side sections far enough to secure the whole together. The hook-bolts h may be put any desired distance apart necessary to accomplish the purpose for Vwhich they are intended 5 but, in construction of buildings inthis manner, I put a bolt through as near to the end of each 'section, where the roof and sides join, as I can with safety, to keep that portion of the building iirmly united. p

The buildin g can be set upon any ordinary kind ot' foundation, care being taken, as in all others, to have it level. To secure it further at the bot- (See Fig. 4.) The tom, if deemed necessary, a sill or rail, S, or its equivalent, can be used.

The roof can be covered, if desired, with canvas or other material; but I prefer to strip the joints with tarred or painted canvas.

The advantages claimed for my invention are: Cheapness of construction, portability, (the pieces being light and few,) and the ease and facility with which it can be put together or taken down in the shortest possible time; also, its capability of enlargement o11 diminution; its construction o11 grooves e', strip W, Washer c, and nut n 01 not necessitating anything more than duplicatits equivalent, substantially as and for the plu*- ing; the sections. pose hereinbefore set forth.

Having thus described my invention, what I FRANCIS M. BAIN. claim as new isl. Hook-bolts h, substantially as and for `the Witnesses: purpose hereinhefore set forth. GEO. C. RAWLINS,
